On which of the following types of roads is it prohibited to do a reversing maneuver?

As a general rule, traffic regulations state that it is prohibited to go in reverse on motorways and dual carriageways, except when it is used as a complementary maneuver to some other maneuver that requires it. So, it could be done as a complement to stopping, parking or incorporating into traffic, provided you do not go farther than 15 meters in reverse or invade an intersection.
